Letters Patent No. 97,650, dated December 7, 1869; `(mtcclaicll November 27, 1869.

GRAIN-laluna.

The Schedule referred to in these Letters Patent and making part of the same. p

`To all whom it may concern y -Be it known that I, S. C. KENAGA, of Kankakee,

in the county of Kankakee, and State of Illinois, have invented certain "new audusefnl Improvements in Grain-Driers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, .which l-make part of thisy speciication, and in which- Figure l represents a vertical section of my improved grain-drierat the line of iig. 2, the conveyer-shaft and conveyers being 4shown inelevation;

Figure 2,21. horizontal section of the same, at the line y 'y of iig. l; and r i Figure 3, a similar section at the line z z of fig. l.

The object of myinventiou vis to provide suitable `means for thoroughly drying? grain, in such manner that heat can be applied `unifoi'u'nly to the whole mass thereof,"or"to any desired degree -to different portions thereof', at pleasure; towhich lends,

My improvements consist in` a case or chest divided by partitions into vertical compartments, and provided Awith a number 0i' perforated dryingloors, one above the other, over each of which suitable conveyerrotates. f 1

Fire-boxes, or heaters, are placed at bottom of the diiferent compartments, andthe heated air therefrom,

` passing through'the ues, `lue-spaces, and perforated oors, dries the grain spread thereon by the conveyers.

Each compartment is provided with a Ventilating;t

door, by-,means of which the 'amount of heat may also be regulated by the admission of cooler air at pleasure.

In the-accompanying drawings, which show a convenient arrangement of parts for carrying out the objects of my invention-- A represents a cylindrical caseor chest, which may be'composed of brick or metal, lined with suitable material to prevent transmission of heat, and is divided, by the partitions a a1 a2,'into two vertical compartments, A1 A2.

In the ease A, above the compartments A1 A2, are cylindrical chambers D D1 D2, having minutely-per- `forated tloors B B1 B2, arranged one above the other, and separated by flue-spaces d d1.

The lower chamber ,D2 has a Hue-space, d2, under that portion oi' it which is over the -compartment A2,

as to keep this last and the chamber D2 completely separated, which line-space d2, as well asrd1, connects with the compartment A1.'

1 Ihenpper flue-space tl communicates `with the division A21 throruglr the flue h.

From the centres of the plates f, forming the tops of thechambers D D1 D2, and the bottoms of the flue-spaces d d1 d2, the `cylinders or chimneys g g1 g2 rise, so as to form, with the'cylindrieal casing of the chambers 1) D1 D2, an annular space on the perforated floors B B- B2, and are the only means of communication between the chambers D D1 D2, and the external air at the top ofthe apparatus.

A central conveyer-shaft, G, hearing in a step, c2, on thepartition a, is rotated by the application. of

-power tothe bevel-wheel e ou its upper end, and'carries conveyers C1 C2 C, provided with inclined blades c1, the conveyers being secured upon the shaft i'n suc-h position as to rotate in close proximity to the upper surfaees'of the respective drying-floors in the annular spaces between the casings ofthe chambers D D1 D2, and the chimneys g g1 g2.

The grain is supplied to the upper floor B, through the feed-spout D1, near its periphery, and the blades of thel conveyer C1 areI inclined in such direction as to spread the grain over itsW surface, and discharge it through the spout b, near its centre, through which it passes to the oor B1. i

The blades of theconveyer G2, which rotate above the floor, being inclined in contrary direction, sweep the grain from the centre to the periphery, and discharge it through the spout b1 to the tloorYB2, whence it'is discharged by the conveyer 02,'whose blades are inclined similarly to those of G1 through the deliveryspout b2, to be packed or removed.

Any desired number of drying-floors may be employed, andby the alternate centrifugal and centripetal action of the couveyers, it will be seen that the grain is thoroughly stirred and spread over a large extent of surface, to be exposed to the action of the heat.

Fire-boxes, or heaters EFE, having grates @suitable for burning coal or coke, are arranged in the compartments A1 A2 respectively, and if more than two compartments should be made, eachmust be provided witlra separate heater.

The heated air from the heater E, as indicated by the arrows, ascends through the compartment A1, from thence through the ue h and iiue-spaces dz and d1, up through the perforations of the tloors B2 and B1, dries the grain thereon, and then passes oft through the chimneys g g1 g2. v

The heated air from the heaterE, as also indicated by the'arrows, ascends through the compartment A2, from thence through the Hue h1 and flue-space d, up through the perforations of the floor B, dries the grain thereon, and passes oli` through the top ofthe drier..

By this arrangement of parts, the heat applied'to the grain on'the Hoor B, can be regulated to any degrec desired, without interfering with that appliedto the grain on the i'loors B1 and B2, and vice versa. l

Openings, which can be closed at pleasure bythe ventil-ating-doors c atare made in the compartments Al A2, for the purpose of admitting cool air, to lower the temperature thereof when necessary.

I do not confine niyself to the precise number of. drying-floors and compartments herein shown, as such can be varied, without affecting the principle of my invention. n

Different degrees of heat can he applied to the floors by proper regulation of the res in the respective heaters, and the doors ai a* enable the temperature to be lowered if it should exceed proper limits.

Having thus fully described my invention,

What I claim therein as" new, and desire to secure by Letters Patent, is

The heating-compartments Al A2, with their nes v In testimony that I claim the foregoing' invention,

I have hereunto set my hand, this 8th day of February, 1869.

S. C. KENAGA.
